我县既是产粮区,又是油料作物花生的重点产区。但由于全年总积温为4,100—4,300℃,春播花生,一年只能种一季,要占去40％的粮食面积;夏播花生,产量很低,质量也差,还影响下茬小麦适时播种;等行麦套种花生,由于共生期间相互影响大,田间管理不便,产量也不理想。我们从七十年代开始逐步试验、示范、总结推广了“大沟麦”套种花生,1982年全县已推广到21万亩,占花生面积的52.5％,增产增收效果显著。
My county is both a grain-producing area and a key producing area for oil-crop peanuts. However, since the annual accumulated temperature is 4,100-4,300 ℃, spring sowing peanuts can only grow one season per year, accounting for 40% of the food area; summer sowing peanut, yield is low, the quality is poor, but also affect the timely sowing of the next crop of wheat ; And other intercropping wheat intercropping peanuts, due to the mutual influence during the symbiosis, field management inconvenience, the yield is not satisfactory. From the seventies of the beginning of our experiment, demonstration, summary of the promotion of the “ditch wheat” interplanting peanut, in 1982 the county has been extended to 21 million mu, accounting for 52.5% of the peanut area, a significant increase in production and income.
